Answer 1

Alfred Wegener used congruent continent shapes, matching fossils, geological formations, and paleoclimate evidence to support his hypothesis of continental drift, proposing that continents were once part of a supercontinent named Pangea.

Step-by-step explanation:

The types of evidence used by Wegener to support his hypothesis of continental drift included a few key observations. Wegener proposed that continents once formed a supercontinent called Pangea about 200 million years ago, which later drifted apart. The evidence he used to support this were:

• The congruent shapes of the continents, suggesting they fit together like pieces of a puzzle.
• Matching fossils of the same species found on different continents separated by vast oceans, such as in South America and Africa.
• Matching geological formations, like mountain ranges, on different continents indicating they were once connected.
• Paleoclimate evidence that pointed to different historical climatic conditions, which was consistent with continents being at different positions from where they are now.

These lines of evidence were crucial for the formulation and support of the concept of continental drift, which later evolved into the widely accepted theory of plate tectonics.
